The invention discloses a realization method for simulating combustion flame of aviation kerosene by using combustion flame of propane, and relates to the technical field of fire safety. By analyzing a combustion characteristic of the aviation kerosene, a corresponding combustion mathematic model is built; and a model algorithm for simulating combustion of the aviation kerosene by utilizing combustion of propane is realized mainly from three aspects of heat release rate equivalence, combustion rate equivalence and flame height equivalence. The heat release rate equivalence shows that heat released in a combustion process is same, and can be represented as the harm degree of fire in the combustion process. The combustion rate equivalence shows that the fuel combustion consumption is same. The flame height equivalence shows that fire intensity of combustion is similar. The propane flow required for simulating the flame height of the aviation kerosene under a certain area is calculated according to the method; and the flame height generated by using a system for simulating a combustion state of the aviation kerosene has relatively high similarity with that of the aviation kerosene.
